Nottingham's 500-metre track produces some of the most uneven trap statistics of any venue in the data, and the contrast between trap four and trap five is particularly striking. Over 42 races, trap four has produced just one winner — a win rate of 2.4%. Trap five, over the same sample, has won 11 times from 42 starts: 26.2%. That's a 23-percentage-point gap between two adjacent boxes at the same track.
Why? Nottingham's track geometry means that trap four sits in an awkward position relative to the first bend — dogs drawn there regularly find themselves on the wrong side of a bunching point, taking interference or losing a length or two through the first turn. The data backs that up in the clearest possible terms. One winner from 42 runs is not bad luck. It's a structural pattern.
Trap five, by contrast, finds a cleaner line through that same first bend, often picking up momentum from the wide draw while the inside runners collide. The average winning time at Nottingham is 28.13 seconds — competitive enough that small positional advantages at the first bend often decide the outcome.
Beyond the trap bias, Nottingham rewards dogs with genuine pace. The grades running today at this track tend to produce tight margins, and the trap statistics suggest that a dog with real ability from trap four is being asked to do extra work to overcome a structural disadvantage. Trap five dogs get the opposite kind of help.
